Whole Berry Bundle
April Soncrant

I am a new owner of a mill and am milling my own flour for the first time. This is so much fun, and the Barton Springs grains are just wonderful. Everything about my order was great, from the customer service, quick shipping, excellent notifications, right to the product itself. Fresh and flavorful. I am very pleased.

Sonora Wheat Berries

Beautiful and Delicious

I use the Sonora Wheat Berries for all my non-yeast baking. Muffins, pancakes and more. I love the golden color and flavor of this wheat. My order was packaged well and the wheat is very clean and ready to mill.

Einkorn Flour

Einkorn Flour

Made Einkorn Flour and White Cornmeal pancakes. Great taste. To hot to bake anything this time of year. Trying some grits for evening meal, topped with eggs. Thank you for service and answering questions about grind on corn.


I love spelt, especially Barton Springs’ spelt. It is very clean, and they ship it so fast. I made banana bread recently, and knowing that spelt is a complete protein, along with fruit, nuts, butter and eggs, you’ve got all the food groups in a delicious slice.

Emmer Flour
